Jurgen Klopp has done an incredible job at Liverpool since becoming manager in 2015.
In four years he's transformed the Reds from a club struggling to reach the top four to Premier League title contenders and Champions League winners.
A lot of it comes down to the money the German has spent to sign world-class talent like Mohamed Salah, Virgil van Dijk, Alisson and Fabinho.
But he's also nurtured players like Trent Alexander-Arnold, Joe Gomez, Andy Robertson and Jordan Henderson, helping them to realise their true potential.
Klopp's transformation of Liverpool's squad is four years in the making and it looks unrecognisable to the team that almost won the Premier League in 2013/14.
Only Henderson remains, with most of the rest being sold by Klopp.
Simon Mignolet's £6.4m move to Club Brugge earlier this week made him the 36th player to be sold by Klopp at Liverpool and marked the completion of his rebuild.
Klopp has performed some miracles in the transfer window down the years and you can see some of them in the list below.

Coutinho's move to Barcelona may have earned Liverpool £142m, but arguably the most satisfying sales were Benteke and Sakho to Palace for a combined £58m.
Benteke has been awful since moving to Selhurst Park, while Sakho was never good enough for Liverpool anyway.
